I just got the PacBell self install kit today. My computers are already networked so I went with the Ethernet DSL modem. In the kit was the modem, a network card, and filters and splitter.
Filters go on all your phones connected to that line. Plug modem in power, wall, and hub, and everything was set.
If you're going to use the network card, you'll obviously need to install that. Or get the USB version.
However, the software package comes from a different location and hasn't arrived, so I've got a DSL modem that's a set and synced, but I can't use it, because I don't have the software, and haven't the foggiest idea how to setup an account.
My opinion is that it's not worth the $200. Once I figured out where I wanted to place everything, it took me a few minutes to run around the house placing filters, and plugging everything in.
